Suppose you are studying a population of bacteria in a lab some of the bacteria are born with a mutation that provides them resi

Naddik [55]

Answer:

The bacteria with the mutation will survive.

Explanation:

In this population, if there is a group of bacteria of the same specie that mutate and this mutation is the expression of antibiotic resistance, this mean that the "mutant bacteria" are going to live spite the action of the drug.

Meanwhile the rest of the population is going to die because these group of living things are susceptible to the antibiotic, that means, they are going to die.

In the other hand, the "mutant" living things, by passing the time are going to reproduce and lead a new generation of bacteria resistant to the antibiotic.

A woman has blood Type A, her baby has blood Type AB: Is it possible that a man who has the blood Type A could be the father? Sh

Wittaler [7]

Answer:

No, it is not possible

Explanation:

Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.

This system is such that;

Type A can only have genotype: iAiA or iAi

Type B can only have genotype: iBiB or iBi

Type AB can only have genotype: iAiB

Type O can only have genotype: ii

According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).

Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)
